Answer:

5 L

Explanation:

We'll begin by calculating the molarity of the CaCl₂ solution. This can be obtained as follow:

Mole of CaCl₂ = 0.5 mole

Volume = 2 L

Molarity =?

Molarity = mole /Volume

Molarity = 0.5 / 2

Molarity = 0.25 M

Finally, we shall determine the volume of the diluted solution. This can be obtained as follow:

Molarity of stock solution (M₁) = 0.25 M

Volume of stock solution (V₁) = 2 L

Molarity of diluted solution (M₂) = 0.1 M

Volume of diluted solution (V₂) =?

M₁V₁ = M₂V₂

0.25 × 2 = 0.1 × V₂

0.5 = 0.1 × V₂

Divide both side by 0.1

V₂ = 0.5 / 0.1

V₂ = 5 L

Thus the volume of the diluted solution is 5 L

Explanation:

The bond between magnesium atoms is a metallic bond while the bond within a crystal of aluminum iodide is an ionic bond.

A metallic crystal consists of a sea of electrons that are electrostatically attracted to positive metal ions. This is the nature of the bonding between magnesium atoms in a crystal of magnesium.

In aluminum iodide, there is a transfer of electrons from aluminium to iodine which is typical of an ionic bond. Electrostatic interaction holds oppositely charged ions together in the crystal of aluminum iodide.

I loved Mako Mermaids too, though I thought the spinoff was lazy with conforming to the canon; how could the pod have inhabited Mako Island for thousands of years but were never seen in H2O?

Answer:

Explanation:

Solid is a hard and not able to flow; not like a liquid or gas. Having no holes; not hollow. Something that is not liquid and gas. Solid has fixed volume but not a fixed shape.

The liquid is something that flows freely; a substance that is not solid or gas.

Gas is a substance that neither liquid nor solid, e.g. air.

Plasma is an electrically neutral ionized gas in an electric discharge; distinctly different from solids and liquids and normal gases.

Therefore, the correct answer is C. solid.

Answer:

A. Liquid

1.Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. 

2.Because predators were able to spot the light moths more easily, the dark moths were more likely to survive and reproduce. ... The peppered moth case is an example of natural selection. In this case, changes in the environment caused changes in the characteristics that were most beneficial for survival

Answer:

5974 g of Na₃P

Explanation:

We determine the reaction:

2Na₃P + 3SrO  →  3Na₂O + Sr₃P₂

2 moles of sodium phosphide react to 3 moles of strontium oxide to produce 3 moles of sodium oxide and 1 mol of strontium phosphide.

We know that 1 mol of anything contains 6.02×10²³ formula units, so:

5.4×10²⁵ formula units . 1 mol/6.02×10²³ formula units = 89.7 moles

This is the amount we have, initially for SrO.

Ratio is 3:2. 3 moles of SrO react to 2 Na₃P

Then 89.7 moles of SrO may react to (89.7 . 2) /3 = 59.8 moles of Na₃P

We convert the moles to mass (mass . molecular weight)

59.8 mol . 99.9 g /mol = 5974 g

Answer:

Explain: In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.

3- compass

Answer:

C.It remains at rest or moves at constant speed in the same direction.

Explanation:

First, remember the Newton's 1st law of motion which states that the object at rest will remain at rest and that in motion will stay in motion with the same speed and same direction unless acted by unbalance forces.

Balanced forces on an object occur when two forces at act on an object are equal in size and act in opposite direction. In this case, a stationary object will stay at  rest while an object moving will continue to move at the same speed and same direction.

An object acted by balanced forces is said to be at equilibrium, thus the state of motion will be maintained.The object will not accelerate. A good example of an object acted by balanced forces is an object at rest or in constant motion such as a car that stopped at red-light signal or a car travelling at a constant speed.

Answer:

Explanation:

If another predator was introduced to this food web, this food web would fail because it won't be balanced well. Let's say the predator eats more food than the eagle. Then the eagle would have less food for itself, and it might go endangered, and vice versa if the eagle eats more. Either way, this would cause almost no worms left and that means there would be an overflow of the rats because there would be no worms for them to be eaten by. This would cause a shortage of crops as well.

Answer:

Limiting reactant: O₂

Excess reactant: NO

Amount of NO₂ produced: 28.75 g

Explanation:

The balanced equation for the reaction between O₂ and NO to produce NO₂ is the following:

O₂(g) + 2NO(g) → 2NO₂(g)

According to the equation, 1 mol of O₂ reacts with 2 moles of NO to produce 2 moles of NO₂.

We first convert the moles of each compound to mass by using the molecular weight (MW):

MW(O₂) = 16 g/mol x 2 = 32 g/mol

⇒ mass O₂ = 1 mol O₂ x 32 g/mol O₂ = 32 g

MW(NO) = 14 g/mol + 16 g/mol = 30 g/mol

⇒ mass NO = 2 mol NO x 30 g/mol NO = 60 g

MW(NO₂) = 14 g/mol + (2x 16 g/mol) = 46 g/mol

⇒ mass NO = 2 mol NO₂ x 46 g/mol NO₂ = 92 g

For the reactants, the stoichiometric ratio is 32 g O₂/60 g NO. Thus, the mass of O₂ required to completely react with 20.00 g of NO is:

mass of O₂ required = 20.00 g NO x 32 g O₂/60 g NO = 10.67 g O₂

We need 10.67 g of O₂ and we have only 10.00 g, so the limiting reactant is O₂. Thus, the excess reactant is NO.

With the limiting reactant, we calculate the amount of product produced (NO₂). For this, we consider the stoichiometric ratio 92 g NO₂/32 g O₂:

mass of NO₂ produced = 10.00 g O₂ x 92 g NO₂/32 g O₂ = 28.75 g NO₂

Answer:

Thymus. This gland makes white blood cells called T-lymphocytes that fight infection and are crucial as a child's immune system develops

Answer:

See explanation

Explanation:

When we are writing chemical reaction equations, we must ensure that such equations are balanced. That is, the number of atoms of each element on both sides of the reaction equation are exactly the same.

After we identify the formula of each compound in the reaction, then we proceed the write the balanced reaction equation as follows;

CuCl2 + 2AgNO3 -------> Cu(NO3)2  + 2AgCl
